"which the following is e snecification This invention relates to improvements in stops for souncl reproducing machines, which are adapted to automatically cause the arrest of rotation of record structure when the playing of a record is completed, so as so nvoicl scratching the record by a: needle or stylus. More particularly this invention relntes to mocliiications of the structure or structures set forbh in my companion appli cations Serial Number 3,?63, filed Jan 1915; Serial Number 36,221, filed June 25, 1915, Serial Number 44,0Q8 filed August 6, 1915, and application executed by me on the 21st day of August, 1915, Serial Number- 50,12 l-, fileo.

The inner end. oi. said e is closed, excepting for n small open in which a. screw adjusting shaft 1% is urnslcd, the inner end of said shaft being tln'czutled into the brake engaging pin 1;, and provided on its outer end with a turning member by which the screw can be revolved by hand. The screw shuft is formed with a shoulder which cooperl5 prevents tuclinai n 'Wcrnent of the screw shaft c e'housing.

oin. 12 entering the threaded ries an index pointer 26,

passage in which the screw the brake engaging pm.

I sound grooves. These numbers are so arranged, as to correspond with the ordinals on the dial 20, so that in order to stop a record when the sound box reaches the'end of its groove, the turning of the screw shaft 14 until the pointer 26 registers with the number on the dial, which corresponds with the number on the record tablet, moves the brake engaging pin 12 into suitable position, so that it will engage the brake releasing lever 3 at the properinstant, and cause the brake to arrest further movement of the turn table instantly when the play ing of the record has been completed.

In Fig. 5 the same construction as illus-. trated in Figs. 3 and 4 is shown, excepting that the dial instead of being horizontal as illustrated in Figs. 3 and 4 is arranged vertically on the-housing, said dial 27 being in the form of a semi-disk without the shaft 4 engagement, illustrated in Figs. 3 and at. This type of construction is shown provided with a split collar 28 extending horizontally from one side of the housing, which enables my improved stop to be clamped to the tone arm 29, (see Fig. 2), immediately adjacent the pivot point upon which said arm swings. This type of stop is thus applicable for use on the conventional type of Victor sound reproducing machine, and is adapted to cooperate with the brake releasing member 30 in the same manner as in the construction illustrated in Fig. 1. It will be observed that the graduations on the dial are readily read from in front of the machine instead of the operator having to look down upon the dial when the dial is hori zontal.

The modification illustrated in Figs. 6 and 7 is of substantially the same construction as illustrated in Figs. 3 and 4, except- 'lng that instead of a toothed pinion being employed, the index arm 31 is in the form of a lever pivoted at 32 between its ends upon the horizontal supporting plate 33, the opposite. end of said lever from that forming the pointer 31 being formed with a longitudil'lal slot 34. in which a. pin 85 carried by the brake engaging pin 36 passes, whereby as the screw shaft 37 is turned by the hand piece 38, the lever 31 is swung upon its pivot and caused to indicate on the dial the position assumed by the brake engaging pin 36. A suitable passage 39 is formed 1n the lower surface of the housing the dial the adjustment of said 40 in which the pin 35 slides freely and the housing 40 is suitably mountedupon the supporting plate 33, leaving a suitable pas sage 41, in which the lever arm 31 1s free to swing as described.

In the construction illustrated in Fig. 8 substantially the same form of stop is illustrated as shown in Figs. 6 and 7, excepting that instead of the dial 42 being arranged in horizontal position, it is arranged vertical in much the same manner as illustrated in Fig. 5, and a split collar 43 is also provided extending laterally or horizontally from the housing, whereby the device can easily and quickly be applied to the conventional type of Victor sound reproducing machine, which is illustrated in Fig. 2.

In all of the structures set forth, it will be observed that a micrometer adjustment is provided for setting the brake engaging pin, whereby accurate and quick adjustment is provided, and whereby the device remains adjusted until intentionally re-adjusted by an operator.

In accordance with the patent statutes, I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative, and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.

Having described my invention, what I claim as new and desire to protect by Lettors Patent is:

1. The combination in a sound reproducing machine having a traveling element, a turn table and bralre mechanism to prevent the table revolving, of a support secured to said traveling element, said support having a graduated dial thereon, a housin carried by said support, a stop member sli ably disposed within and through one end of said housing and adapted to impinge against and set said brake mechanism, means having screw threaded engagement with said stop.

member whereby said stop may be positioned to actuate said brake termined time, and means mounted upon said support actuated by the movements of said step engaging means to indicate upon stop.

"2. The combination in a sound reproducing machine having a traveling element, a turn table and brake mechanism to prevent the table revolving, of a support secured to said travelingelement, said support having a graduated dial thereon, a housing carried by said support, a stop member slidably disposed within and through one end of said housing and adapted to impinge against and set said brake mechanism, means having mechanism at a predescrew threaderf, engagem- I the table from revalving, f 21 support 'nvmember Whezreby S 301 may mg a (11:11 pmvldecl W m umbered gradua- '10 1s L aid supporfi being a. .ap'ied for attachment to said traveling eiemenu, swp means mova 01a ransversely of said supp It to nontact with and set said brake machanism, a 40 to actuate sai brake me" termined time, imdmeans piv upon said support astuats i meats 0f said stop engagix v cute upon the dial the ad m member rotatab'iy meunted 27.3111 said supstop. port and mvmg tales co ing threadeci @11- 1 smmd rapmclum gagement th said stop for moving dammit, a 51m same, and means alc'tuzlted E y one of said z'cveflt i c'iicate awn said dial the s.
